Based on Marvel Comics, “Eternals” is a superhero action film revolving around the Eternals, a group of immortal beings with superhuman powers, who have secretly lived on Earth for thousands of years. They are tasked to defend Earth from the Deviants, a monstrous race who are the arch enemies of the Eternals.
The film is classified M18 with the advisory “Some Mature Content”.
The film contains some homosexual references and depictions. One of the male Eternals is shown to have a same gender family unit including a child. In a later scene, the two same gender partners embrace and kiss before the Eternal leaves to carry out the mission to save Earth. This would be more appropriate under the M18 Classification Guidelines which allow “non-explicit depictions of mild sexual activity or acts of intimacy (e.g. kissing and hugging) between persons of the same gender”.
The film also contains a scene depicting sexual intimacy between a man and woman, where the camera focuses on their upper bodies.
In addition, the film contains some scenes of violence where the Eternals fight the Deviants and each other with energy beams or weapons. Some injuries are depicted such as slashing or stabbing with blood spurts, but the camera cuts quickly without lingering on these details.
